UK eSIM: Data Only or Calls & SMS

UK travel eSIM: choose data only or a UK number with calls and SMS

Check London train times, navigate Edinburgh and stay in touch during your UK trip with AloOui. Choose fixed data, Unlimited Lite, Unlimited Essential, Unlimited Plus, True Unlimited data-only options, or True Unlimited for 30 days with 500 minutes and 500 SMS. Select the exact plan above: calls, SMS and a UK number are included only on the options that list them. Your QR code is delivered by email after purchase.

Key facts

• Coverage: United Kingdom: England, Scotland, Wales and Northern Ireland. This is not a Europe roaming plan.
• Fixed data: 1GB/7 days, 2GB/15 days, or 3GB, 5GB, 10GB, 20GB, 50GB and 100GB/30 days. Each allowance is for the whole plan, not per day.
• Unlimited Lite: 1GB/day high-speed, then up to 512 kbps for the rest of that day.
• Unlimited Essential: 1GB/day high-speed, then up to 1.25 Mbps for the rest of that day.
• Unlimited Plus: 2GB/day high-speed, then up to 2 Mbps for the rest of that day.
• True Unlimited data only: unlimited mobile data with no daily data cap, no total GB allowance to track and no automatic speed reduction after a set amount of data. Choose 5, 10, 15 or 30 days for heavy usage, remote work or business travel.
• True Unlimited with calls and SMS: the same freedom to use mobile data without a daily cap or usage-triggered throttling, plus a UK number, 500 minutes and 500 SMS for 30 days. Calls and SMS have their stated allowances.
• Activation: travel-plan validity begins when the eSIM connects to a supported destination network, not installation alone.
• Compatibility: an eSIM-compatible, carrier-unlocked device is required. Check your exact model and regional version.
• Delivery: QR code by email after purchase. No physical SIM or ID verification is required for the AloOui purchase.

Compare UK travel eSIM plans

Lite, Essential and Plus have daily high-speed allowances followed by reduced speeds. Actual speed depends on signal, congestion, device and location; no tier guarantees a particular connection speed.

True Unlimited for heavy usage and business travel

Work, stream and stay connected without counting gigabytes or waiting for a daily allowance to reset. True Unlimited gives you mobile data throughout your purchased validity period, with no daily data cap, no total GB allowance and no automatic slowdown triggered by using a set amount of data. It is a practical choice for frequent video meetings, cloud-based work, large file transfers, streaming and data-heavy UK trips.

Choose True Unlimited data only if you primarily use online tools and messaging apps. Choose True Unlimited with 500 minutes and 500 SMS if you also want a UK number for speaking with clients, arranging appointments, contacting hotels and receiving callbacks. The 30-day option combines unlimited data with clearly defined calling and texting allowances.

No usage-triggered throttling is not a guaranteed speed: performance still depends on your device, signal and network conditions. Fair-use rules against abuse and the purchased plan's hotspot terms still apply.

Which UK eSIM should I choose?

Maps, tickets and messages: fixed 3GB or 5GB suits lighter use between Wi-Fi connections. Balanced daily travel: Essential provides 1GB of high-speed data each day. More uploads and shared data: Plus doubles that daily high-speed allowance to 2GB. Heavy usage or business travel: choose True Unlimited to use data without tracking daily or total allowances. Business contacts and local calls: choose the 30-day True Unlimited option with a UK number, 500 minutes and 500 SMS.

Fixed-data options with a UK number, calls and SMS

Choose these directly in this product's selector. Each includes a UK number and the listed total allowances.

• 1GB/7 days: 20 minutes and 20 SMS.
• 2GB/14 days: 40 minutes and 40 SMS.
• 5GB/30 days: 100 minutes and 100 SMS.
• 10GB/30 days: 200 minutes and 200 SMS.
• 20GB/30 days: 300 minutes and 300 SMS.
• 50GB/30 days: 450 minutes and 450 SMS.
• True Unlimited/30 days: 500 minutes and 500 SMS.

Data-only plans support internet-based calling and messaging apps but do not include native calls, SMS or a UK number. Check the purchased calls/SMS option's permitted calling destinations and exclusions. Receiving SMS does not guarantee verification-code acceptance by every bank, app or website.

UK networks and hotspot sharing

Network access varies by selected plan. The travel range lists Three UK, O2 UK and Vodafone UK with 4G/5G capabilities on applicable options. The True Unlimited data-only and 500-minute/500-SMS option records list O2 UK, with network generation unspecified; do not assume the same network or 5G entitlement for every option. Reception varies in rural areas, inside buildings and along travel routes.

Hotspot sharing depends on the selected plan, device and network. Shared usage counts toward applicable allowances; reduced speeds on daily tiers also affect shared data. Do not assume unrestricted tethering or guaranteed video-call performance.

Install before departure, activate in the UK

1. Check that your exact device model and regional version support eSIM and that your phone is carrier-unlocked.
2. Install the emailed QR code over stable Wi-Fi and follow the order's instructions. Label the line AloOui.
3. Restart after installation. In the UK, enable AloOui, select it for mobile data and enable data roaming on that line as instructed.

Installation alone does not start travel-plan validity. Validity starts when the eSIM connects to a supported destination network. Keep data roaming off on your home line and avoid automatic data switching. Follow the purchased calls/SMS option's specific setup instructions.

APN and troubleshooting

Follow the APN and credentials supplied with your order. This product's current setup guidance lists data.esim with username and password blank where manual setup is needed. Confirm AloOui is selected for mobile data and roaming is enabled as instructed, save/select the APN and restart or briefly toggle airplane mode.

Use automatic network selection first; if needed, try a supported partner in your delivery instructions. Keep the installed eSIM and your QR code private. Do not delete the profile while troubleshooting. Contact the AloOui Help Center with your order details, phone model, location and error message. AloOui provides 24/7 human support.

Also visiting Europe? Compare UK & EU Prepaid

For a UK-and-Europe itinerary with a UK number, compare these separate fixed-data purchases. Each includes 50 minutes and 50 SMS, usable from any of the 30 included destinations to numbers in any of those destinations. They do not add European roaming to the UK plans above and are not True Unlimited.

• UK & EU: 2GB for 7 days
• UK & EU: 5GB for 14 days
• UK & EU: 10GB for 30 days
• UK & EU: 20GB for 30 days

Included destinations: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and United Kingdom.

Check every stop. Norway, Iceland and other destinations outside this list are not included. Data is one total pool shared across the purchased duration and included destinations, not a daily allowance. Calls/SMS to unlisted destinations and premium-rate services are not included. Crossing a border does not reset the data pool or package validity.

For these UK & EU products, the UK number is valid for six months only and the maximum top-up window is six months. Those periods are separate from the purchased 7-, 14- or 30-day package and do not supply six months of included allowances. Confirm actual expiry and compatible top-ups; do not assume a top-up extends the number or resets the window.

Prices may change. Always check the product page for the latest prices before purchasing.

Other separate regional data options

Compare Europe+, Europe Extra, Europe + USA or Europe + USA + Business Hubs. For wider routes, compare Global, Global Light, Global Standard and Global Max. Check each product's own destinations and terms: these are separate purchases, not added coverage on your UK plan.

UK eSIM and UK & EU FAQs

Does installation start travel-plan validity?

No. Travel-plan validity starts when the eSIM connects to a supported destination network, not installation alone. Follow the purchased calls/SMS option's specific activation terms.

What does True Unlimited mean?

Unlimited mobile data for the purchased duration, with no daily cap, total GB allowance or automatic slowdown triggered by using a set amount. Actual speeds vary; fair-use rules against abuse apply.

Is there True Unlimited without calls and SMS?

Yes. Select the data-only V2 options for 5, 10, 15 or 30 days. They do not include native calls, SMS or a UK number.

Which selector names identify data-only True Unlimited?

United Kingdom Unlimited 5 Days V2, 10 Days V2, 15 Days V2 or 30 Days V2. Use the direct duration links in the comparison table. Standard Unlimited options without V2 belong to the daily Lite family.

Can I get True Unlimited with calls and SMS?

Yes. Select True Unlimited 30 Days 500 SMS 500 min for True Unlimited data, a UK number, 500 minutes and 500 SMS.

Are the 500 minutes and SMS unlimited?

No. Data, call minutes and SMS are separate. The number-enabled option has the stated 500-minute and 500-SMS limits.

Does True Unlimited reset daily?

It has no daily high-speed pool to reset. Lite, Essential and Plus have their own daily high-speed allowances and reduced-speed rules.

Is Plus the same as True Unlimited?

No. Plus provides 2GB/day high-speed, then up to 2 Mbps, resetting daily. True Unlimited has no daily data cap or usage-triggered slowdown.

Is True Unlimited the same as Premium?

No. Premium on other products can have a whole-plan high-speed pool and reduced-speed continuation. Use the exact UK True Unlimited terms shown here, not another destination's plan-family rules.

Which plan suits lighter use?

Compare fixed 3GB or 5GB for maps, messages and bookings between Wi-Fi connections. Choose enough total allowance and purchased duration for your itinerary.

Which option suits balanced daily travel?

Essential includes 1GB/day high-speed, then up to 1.25 Mbps. Compare its duration and current price with your needs.

Is fixed data a daily allowance?

No. Each fixed-data pool is total data for the whole plan. It does not refill daily.

Does fixed data continue at reduced speed after exhaustion?

No reduced-speed unlimited continuation is included in the fixed-data options described here.

Can a larger fixed pool extend expiry?

No. Remaining data does not extend the purchased duration. Match both the allowance and the validity to your trip.

Can I use these UK options in France or Spain?

Not as part of this UK country product. Compare a separate UK & EU or other regional purchase explicitly listing your destinations.

Can I activate or use UK service overseas?

This is UK coverage, not overseas service. Follow the exact order's activation rules; installing a profile elsewhere does not establish service there.

Which network is listed for True Unlimited?

O2 UK is listed for the True Unlimited data-only and 500-minute/500-SMS records. Network generation is unspecified.

Is 5G guaranteed?

No. Access depends on the purchased option, device and location. Do not extend another UK variant's technology listing to True Unlimited.

Is reception guaranteed in the Highlands or on trains?

No. Rural routes, tunnels and buildings can have variable reception. Save maps, tickets and important details offline.

Can I share a hotspot with my laptop?

Confirm permission and any limits for the exact option before purchase. Device and network support matter; do not assume unrestricted tethering from unlimited data alone.

Do data-only plans support internet calling apps?

They supply data for internet-based calling and messaging where connectivity and the app permit. They do not add ordinary phone calls, SMS or a UK number.

Can I keep my existing number?

If your device supports the line arrangement, retain your home line as needed. Its calls, SMS and roaming charges remain separate. Disable unwanted data switching and home-line data roaming.

Will every bank accept a supplied UK number?

No guarantee applies. Each bank, app or website controls number acceptance and verification-message delivery.

Are international or premium-rate calls included?

Check the exact calls/SMS option's permitted destinations and exclusions. A listed minute allowance does not establish every call type.

What device do I need?

An eSIM-compatible, carrier-unlocked device. Check the exact model and regional version rather than relying on the brand alone.

Can I install before travelling?

Install over stable Wi-Fi using the purchased instructions. Installation and activation are distinct; follow the exact number-enabled service terms where applicable.

What manual APN is listed?

data.esim, with username and password blank where manual setup is required. Save and select it; follow order-specific instructions if different.

Which line should I use for calls and SMS?

Select the intended number-enabled line according to your device and order instructions. The data-only line does not provide native calling or SMS.

Should I delete a profile if data fails?

No. Keep it installed while checking setup, service validity and signal and contacting support.

Can I reuse the QR or move the eSIM to another phone?

Do not assume transfer, reinstallation or QR reuse is supported. Ask support before deleting or changing devices.

What do I check if True Unlimited stops connecting?

Check the enabled data line, UK location, purchased duration and APN/roaming settings. Try airplane mode briefly or restart. There is no fixed GB balance to exhaust on True Unlimited.

What if calls stop but data works?

Check the chosen calling line, permitted number type and remaining minute allowance separately. Data being unlimited does not remove call or SMS limits.

What UK & EU options are available?

Separate prepaid products offer 2GB/7 days, 5GB/14 days, 10GB/30 days or 20GB/30 days, each with a UK number, 50 minutes and 50 SMS.

Are UK & EU plans True Unlimited?

No. They have total fixed-data pools and no unlimited-data continuation.

Does UK & EU include all European countries?

No. Only the 30 destinations listed in the UK & EU section are included. Check every itinerary stop.

Are Norway and Iceland in UK & EU?

No. They are not in this range's 30-destination list. Another regional product may differ; check it separately.

Are Switzerland and Turkey in UK & EU?

Yes. Both are in the recorded 30-destination list, alongside the UK and the other listed countries.

Where can the UK & EU minutes and SMS be used?

From any of the 30 included destinations to numbers in any of those destinations. Unlisted destinations and premium-rate services are excluded.

Does choosing UK & EU 20GB increase the call allowance?

No. Each of the four products includes 50 minutes and 50 SMS. Larger data does not add more minutes or messages.

Does crossing a UK & EU border reset data or validity?

No. The total pool is shared across included destinations and the purchased duration continues.

Does six-month UK-number validity mean six months of data?

No. For UK & EU, the number is valid for six months only while the package lasts its purchased 7, 14 or 30 days. Included allowances are not extended to six months.

Does a top-up reset the UK & EU number's expiry?

Do not assume it does. The maximum six-month top-up window is separate from number and package validity. Confirm actual expiry and compatible options.

Is the six-month top-up window permission to delay activation?

No such conclusion follows from that window. Follow the purchased order's activation instructions.

Does exhausting UK & EU data also exhaust unused minutes?

Data, minutes and SMS are separate allowances. Their use remains subject to package validity and purchased service terms; data exhaustion alone does not establish that unused calls or SMS have ended.

Are UK & EU and Europe Calls & SMS identical?

No. They are separate products with different recorded destination lists and number/calling information. Do not substitute one product's terms for the other.
